Title: Biomass prepn. by Methylomonas species cultivation on methanol - continuously in submerged aerobic culture diluted in one or two steps
Inventor: WAGNER FRITZ PROF DR
IPC: C12N1/32
Filed: 1979-09-27
Abstract: Two processes, (A) and (B), are claimed for preparing bio-masses having variable cell compsn. and cell yield. In process (A), a growing submerged culture is generated continuously, opt. with stirring, in an aerated reactor, under aerobic conditions, with the obligate MeOH-utilising micro-organism Methylomonas sp. DSM 580, using MeOH as the only C- and energy-source and inorganic nutrients. Air or O2-enriched air is supplied to this system at 20-45 deg.C. In first step, (i), the continuous submerged culture is increased gradually up to dilution rate 0.45/hr. until equilibrium sets in with constant cell yield. In the 2nd step, (ii), the dilution rate is reduced gradually after the setting-in of the equilibrium, the dilution rate differences being greater than in the 1st step. The dilution rate is reduced until (a) cell yield rise achieved is 0.65 as opposed to the constant cell yield of 0.45 in 1st step, (b) raw protein content obtd. is 86 wt.% and nucleic acid content is only 12 wt.%, w.r.t. cell dry mass. The cell suspension formed is drawn off continuously and separated and the supernatant material is recycled, partly or completely. In process varient (B), the continuous submerged culture is increased gradually in 1st step (i) at a nutrient medium dilution rate of 0.05/hr, in steps such that in the equilibrium condition, MeOH concn. is no higher than 1600 ppm., until the dilution rate reaches 0.6/hr and nucleic acid content is 28 wt.% w.r.t. cell dry mass. The 2nd step, (ii), drops out. The cell suspension formed is continuously drawn off and sepd., and supernatant material is recycled. Bio-mass of process (A) is partic. useful as single cell protein. Bio-mass of process (B) is used in the prepn. of nucleic acid or other cell contents.

Title: Optical telemetering appts. for e.g. gas measurements - has signal and evaluation data carrier conductors contained in same cable with cross talk eliminated by filter
Inventor: MITTER NORBERT DIPL PHYS DR
IPC: A61B5/083
Filed: 1979-12-22
Abstract: The measuring appts. has a sensor section (1) containing an incandescent lamp transmitter (7) and a receiver (8), this section (1) being connected to a sine wave A.C. generator (4) via a cable (2). The object to be measured e.g. a gas under examination, is placed between the lamp (7) and receiver (8). The lamp (7) is connected to the A.C. generator (4) by a supply lead (10) and the receiver is connected to the evaluation circuit (5) by a signal conductor (11). The frequency of the A.C. generator (4) modulates the lamp voltage and forms the excitation frequency which since the lamp (7) is polarisation independent, is emitted as light at double the frequency. This modulated light ray passes through the object to be measured, and arrives at the receiver (8), which transmits a signal voltage via the signal conductor (11) and pass filter (6), to the evaluation circuit (5). Since both signals are transmitted in a common cable (2), cross-talk is eliminated by the filter.

Patent DE-3025112-A1 (DE)
Title: Control of series-connected, forced-commutated converserters - using common but independent variation of ignition and extinction angles
Inventor: FALK PETER ING GRAD
IPC: H02M7/757
Filed: 1980-06-30
Abstract: The propsed control gives soft controlled starting and continuous operation with controlled conduction angle in both rectifier and inverter operation. In all series connected bridges (I,II) the main thyristor (1,1',2,2') firing delay angle (alpha) is controlled by a single common regulator. Similarly for the auxiliary thyristors (3,3',4,4') in the turn-off circuits, the extinction angle (beta) is under the control of one common regulator. At start up, the firing angle of the main thyristors is suppressed and the extinction angle, i.e. the firing angle of the auxiliary thyristors, (beta), is gradually changed from zero to max. (90 deg.). At this value the main thyristors are triggered at max. delay angle (alpha=90 deg.). Then the angles are moved respectively towards their min. values, at the same rate, until the required output is achieved from the bridge assembly. The relationship between the angles may also be controlled to give the best possible a.c. line side power factor.

Title: Insulating layer or filling esp. of polystyrene foam spheres - coated with adhesive and blown into position
Inventor: HOFFMANN HELMUT
IPC: C04B30/00
Filed: 1980-11-27
Abstract: A method of applying insulating coatings and/or filling cavities consists of encasing components or particles of insulating material in adhesive and bonding them together to form the adhesive layer. The adhesive coating is applied immediately before, during or after the particles or granules are assembled to form the coating. Pref. insulating material consists of polystyrene foam particles. The particles may be introduced and compacted by pumps, blowers or vibrators. Simultaneously with the application of the adhesive coating the insulating particles may be impregnated with fire-retarding agent and treated with chemicals to prevent their consumption by animals, decay, fungus, etc. Before the cavity is filled with the insulating particles, its surface may be treated with a sealing material and/or it may be closed with such a material afterwards. The process may be used for filling cavities, such as roof spaces, with insulating material in a single operating stage and requires only inexpensive equipment. The only loads applied are by self-weight and the stream propelled by the blowers.

Patent DE-3102687-A1 (DE)
Title: Loading appliance
Inventor: BROESIGKE MICHAEL ING GRAD
IPC: B66C23/60
Filed: 1981-01-28
Abstract: A loading appliance with a derrick boom held at the top end (derrick-boom peak) by two sets of topping-lift tackle and supported at the bottom end by a gooseneck-pin bearing. The sets of topping-lift tackle are run from the derrick-boom peak to the ends of a rotatably mounted mast spreader. The hauling parts of these two sets of topping-lift tackle as well as of the loading tackle are to be run through the mast carrying the rotatable spreader in such a way that the ropes do not touch at any of the boom positions occurring. The problem consists in the fact that the forces in the hauling parts of the topping-lift tackle constantly change. Each hauling part of the topping-lift tackle is run from the respective topping-lift block located on the mast spreader via a swivel guide block at the derrick-boom peak to the boom side opposite the tackle and from there as far as possible in parallel via a rotary head connected to the mast via a rotary connection through the axis of rotation of the spreader into the mast (see Fig. 1). The hauling part of the loading tackle is likewise run around the mast via the rotary head. <IMAGE>
